I hope cars will do this once we’ve gone electric. Imagine how long you could keep a car if you can swap out a motor with a jack and a socket wrench.

- dsfyu404ed 8y agoThe unsprung mass of hub motors makes them terrible for handling, especially at speed (military vehicles top out at "slow person in the right lane" speeds). When you've got a teardrop shaped turd (or economy car, whatever your preferred pronoun is) that's riding 2in off the ground (because how else are you going to be aerodynamic enough to deliver reasonable range) and nearly nil suspension travel (relative to anything expected to operate off road) drive-train and power transmission packaging isn't really an issue (whereas that was the primary issue solved here by going electric). You should expect to see centrally mounted motors driving the wheels via CV shafts as the dominant EV power-train for the foreseeable future.
